Use relative frequencies from data to estimate probabilities of events joined by 'and', inclusive 'or' and exclusive 'or'.
Worked example
A fair coin is flipped and a fair six-sided die is rolled. What is the probability of getting heads AND rolling a 1? Write your answer as a fraction.
Answer: 1/12
Why: P(heads) x P(rolling 1) = 1/2 x 1/6 = 1/12
